Abstract
In two consecutive years, the effects of pre-harvest conditions on bioactive compounds of Elsanta fruits were evaluated in open-field.
The content of total phenols and the antioxidant capacity (TEAC) were highest in 2006, when temperature and irradiation were higher during the last period of fruit development in comparison to 2007. Both parameters, total phenols, and the antioxidant capacity, as well as ascorbic acid were influenced also by the sampling date.
Variation of leaf:fruit ratio affected yield and fruit weight.
A close leaf:fruit ratio induced high levels of total phenols, TEAC, and soluble solids, but did not influence the content of ascorbic acid.
